Diamond Kata

The Diamond Kata is a TDD exercise. We have already provided a small collection of unit tests that correctly assert the expected behaviour of the application.

The task is to get all the tests passing and have the code generate the expected string for a given single character input.

Examples

input:
  A
output:
  A

input:
  B
output:
  _A_
  B_B
  _A_

  __A__
  _B_B_
  C___C
  _B_B_
  __A__

input:
  E
output:
  ____A____
  ___B_B___
  __C___C__
  _D_____D_
  E_______E
  _D_____D_
  __C___C__
  ___B_B___
  ____A____

Usage

To run the tests you need to do the following:

  1. Ensure you are using a compatible ruby version (>= 2.3.0)
  2. bundle install
  3. bin/rspec
